连续采煤机截割机构截割参数与工作过程的可视化研究
|
摘要
连续采煤机是用在不适合长壁开采的不规则块段、边角煤以及掘进工作面巷道的重要设备,逐渐成为提高矿井综合效益必不可少的手段,是现代化矿山设备的发展方向。截割机构作为连续采煤机与煤岩接触、完成截割任务的装置,对整机的性能、效率和工作可靠性有直接影响,是连续采煤机设计质量和工作性能的关键。
本文通过对连续采煤机截齿排列原则与形式分析、切屑图形成过程及作用、截齿受力与滚筒载荷模型的分析,研究了各因素之间的相互关系。在上述研究的基础上,利用VB6.0可视化设计系统,编制相应的软件程序。通过在VB6.0可视化界面中输入不同的几何参数和运动参数,完成连续采煤机截割机构的可视化设计,并输出各种设计参数下的截齿排列图、相应的切屑图、截割机构的载荷和力矩曲线。文中建立了连续采煤机截割机构的设计理论和方法,研究了各种参数对连续采煤机截割机构性能的影响。其结论对截割机构的设计有一定的指导作用,对提高连续采煤机设计质量和手段有重要意义。

It is developing direction of modern mine equipment .As a device of contacting with coal and accomplishing cutting assignment, the cutting mechanism has an important influence on cutting function, efficiency and reliability of a continuous miner and is crucial to design quality and work function of continuous miner.
The relations between factors are studied according to analyzing the principles and shapes of pick arrangement, forming breakout pattern, and analyzing load models of picks and drums. Based on mentioned study, the programs are drawn up by using VB6.0 visual design system. The visual designs of the continuous miner operating mechanism are accomplished by imputing different parameters of geometry and movement in the visual interface. Kinds of the pick arrangement, the breakout pattern and the curves of load and moment on operating mechanism are output. The design theories and methods are established, and the influence of every parameter on function of continuous miner operating mechanism is researched. The conclusions have great effect on operating mechanism design, and it is crucial to improving design quality and method of continuous miner.
